Embodiment 1

[0017] Embodiment 1 adopts the cultivation method of the present invention to carry out cultivation in Zhanjiang East Island Experimental Base.

[0018] Select the experimental ponds as 7# and 8# respectively, with an area of ​​800m 2 , the pool is 2.0m deep, with sandy mud bottom, with a central drainage system and connected to the water treatment system. After harvesting the shrimps, drain the pond water, let the sun shine until the bottom of the pond cracks, and thoroughly remove the silt and organic matter at the bottom of the pond, barnacles on the pond wall, etc. One month before stocking, use 70-100 kg of quicklime per mu, evenly distribute it on the bottom of the pond, plow and expose to the sun. Enter the water to 20-30 cm. Chlorine preparations are used to disinfect the bottom of the pool. The effective chlorine concentration is 30 g / m3. The whole pool is sprayed with clear pond drugs to kill fish, shrimp, crab eggs, bacteria, viruses, etc.

Abstract

The invention discloses a method for controlling a white spot syndrome by culturing hybrid giant tiger groupers and marsupenaeus japonicas in a mixed mode. The method comprises the steps that marsupenaeus japonicas seeds with the overall length of 0.8-1.0 cm are put into a pond, the putting quantity is 70,000-80,000 per mu, the hybrid giant tiger groupers with the body length of 8-10 cm are put into the pond when the marsupenaeus japonicas seeds are cultured until the body length of each marsupenaeus japonicas seed is 4-5 cm, and the putting quantity is 10-15 per mu. According to the method, according to the life habits of the hybrid giant tiger groupers and the marsupenaeus japonicas, by putting the hybrid giant tiger groupers in the appropriate density and appropriate specification into the high-density intensive culturing pond of the marsupenaeus japonicas, occurrence of the diseased and dead marsupenaeus japonicas can be reduced in the marsupenaeus japonicas culturing process, a good ecological culturing environment is supplied to growth of the marsupenaeus japonicas, the survival rate of the marsupenaeus japonicas is increased, the incidence is decreased, the culturing success rate is high, and the method is suitable for development of scale culturing of the marsupenaeus japonicas in China.

Description

technical field [0001] The invention relates to a method for controlling white spot syndrome by polyculture of pearl grouper grouper and japonica prawn, belonging to the technical field of aquaculture. Background technique [0002] Shrimp aquaculture is the pillar industry of marine aquaculture in my country. It has developed rapidly in recent years, and its annual output has remained at about 1.3 million tons. However, the stocking density is constantly increasing, the breeding environment is deteriorating, and the disadvantages such as high incidence of diseases are becoming more and more prominent. The problem of prawn diseases is still the main bottleneck in the development of prawn farming. The main measures to solve the problem of prawn diseases include improving the disease resistance of prawns, improving the breeding environment of prawns and cutting off the transmission route of prawn disease pathogens. However, since the outbreak of White Spot Syndrome (WSS) in 1...
